The POC Ws Motion Air L/S Jersey is a long-sleeved mountain bike shirt designed for female cyclists seeking optimal performance and comfort during extended rides. This technical jersey combines advanced moisture management with strategic ventilation to regulate body temperature across varying trail conditions. Constructed from lightweight, breathable fabrics, the garment features targeted mesh panels in high-heat zones to enhance airflow while maintaining full coverage protection. The ergonomic cut follows natural body movements during cycling, with articulated sleeves and a dropped tail design that prevents riding up while in the seated position. Flatlock seams minimize chafing against skin and backpack straps, making this jersey suitable for multi-hour trail sessions. The fabric composition includes stretch materials that provide freedom of movement without compromising the garment's shape retention. Practical features include a full-length front zipper for ventilation adjustment, a secure rear pocket for essential trail items, and reflective elements for low-light visibility. The uranium black colorway offers a versatile appearance that coordinates with various cycling kits. Available in size XS, this jersey represents POC's commitment to developing technical apparel that addresses the specific demands of mountain biking. The model number 53319 identifies this specific iteration within the Motion Air series, which focuses on balancing protection with breathability for trail riding applications. Care instructions recommend machine washing at 30°C with similar colors and avoiding fabric softeners to maintain the technical properties of the materials. This jersey is intended for use in mountain biking disciplines where temperature regulation and comfort during sustained physical effort are primary considerations.
